I agree with that. One thing I would say is in Frontier, there were certain systems where you always felt entirely safe, notably Sol and Barnard's Star. It would be good to have the odd attack happen in those systems. Following on from that, it would be good to have more police patrols in deep space, so that 'someone help me' actually does something...
I agree. I'd imagine the core/safe systems to be well policed, but only offer the chance for really very small profits per item - so those that are making money in the core systems are hauling hundreds or thousands of tonnes of cargo and making a few credits per tonne.
Starting out with a much smaller ship of course, making your name and your fortune at a faster pace would require you to venture slightly further afield and take more risks.
It would be good to see that there's no guarantee of safety even if 'safe' space but a guarantee of a police response, faster and with more/better ships - so piracy would still be possible but you'd have to be quick about it.
